It depends on which one you choose. There are four sled racing games you can play, and one has four tracks, one has three tracks and two have only two tracks.

if you just count them you will know that there are four

4 sled race tracks

4 to be exact. 1 for 4 players, 1 for 3 players, 1 for 2 players, and another for 3 players. You can buy game upgrades for that game. It's the toboggan sled for members only. It's 400 coins I think. Hoped this helped!
There are four sled runs in Club Penguin: Bunny Hill (2 penguins can sled against one another), Express (2 penguins also), Penguin Run (3 penguins), and Ridge Run (4 penguins).

dog sled racing
There are many websites where someone can purchase snowmobile tracks for a sled. Some examples of websites where one can purchase some are Camoplast, eBay and Amazon.
It depends. I, for example, have a one-dog sled team (she's VERY big) but, if you're not racing them, and they are not giants, I suggest two or three.
